My newest Samsung didn't have Facebook and it was Google that asked what apps I wanted to have on initialization. You can uninstall Facebook if you downloaded fro the galaxy store. You can uninstall almost all the Samsung apps and can disable/hide the others.
Can you uninstall safari from iPhone? The answer is no. Can you uninstall siri? No, you can disable it just as you can with Bixby The "bloat" people talk about are present on both ecosystems.
